Возможно получить количество передаваемого трафика, используя android.net.TrafficStats.Вот реализация этой идеи, которая измеряет восходящую и нисходящую скорость передачи.Вы можете измерить скорость мобильной сети, передав TrafficSpeedMeasurer.TrafficType.MOBILE конструктору TrafficSpeedMeasurer, в противном случае использование TrafficSpeedMeasurer.TrafficType.ALL приведет к измерению общего трафика (WiFi / Mobile).Также, установив SHOW_SPEED_IN_BITS = true в MainActivity, вы можете изменить единицу измерения скорости на bit с в секунду.
